Recently I did my first "build" on a mountain bike I got for free, very green to this whole ordeal. Specs and questions/concerns are as follows (did a lot of ADHD searching but no solid answers on the specific things I'd like to know)
Bicycle: K2 Zed 4.4 Reflex, not too sure on specs since there's not much information on the internet for K2 in general and I couldn't find much on this specific model. 8 speed rear cassette with integrated shifter
Motor: Bafang BBS02 52t from LunaCycle with DPC-07 display
Battery: Hailong style 52V 20Ah 30A battery from Walmart (mounted on top in front of seat)
Brakes: Front JFOYH 4-piston hydraulic 160mm from Amazon, Rear is still stock cable caliper style.
MOTOR QUESTIONS AND CONCERNS
The chain keeps coming off from bumps, I've read that its more than likely chain alignment and can be fixed with guides, but can that also be remedied with getting a smaller chainring? Like going from a 52t to maybe 42t or smaller?
Is there any way to get multiple center chainrings like how the bike had before the conversion? Never seen a 24 speed BBSxx but still wondering if its possible even theoretically.
I've seen many posts on ES and other blogs on external controllers for the BBSHD but is it possible to mate a BBSHD controller onto a BBS02? Or even an external controller to get 30A on a BBS02 like a phaserunner?
I'm trying to get the most of this BBS02, without upgrading to a BBSHD or bigger for budget reasons. Breaking it is no problem however, got that car tinkering personality where if it breaks, its getting upgraded. Just wanna know if any of these things can be done, either if its been done or if its possible in theory.
Thanks in advance!
